The advantage in investing bitcoin is that you will earn a profit that will completely change your life. That is, if you know how to manage your bitcoin investment like selling it only when the price is high and hold it while the price is low.
Because the price of bitcoin is not stable, if you buy at the right time and not long after it is sold again when the price rises high, then a big profit will be obtained. But when buying at the wrong time, the price drops then there is no other choice, that is HODL until the price rises again as predicted. According to me, bitcoin investment is still profitable
